SCENARIO 14-6
One of the most common questions of prospective house buyers pertains to the cost of heating in dollars (Y) . To provide its customers with information on that matter, a large real estate firm used the following 2 variables to predict heating costs: the daily minimum outside temperature in degrees of Fahrenheit ( X1 ) and the amount of insulation in inches ( X 2 ) . Given below is EXCEL output of the regression model.

To provide its customers with information on that matter, a large real estate firm used the following 2 variables to predict heating costs: the daily minimum outside temperature in degrees of Fahrenheit ( X<sub>1</sub> ) and the amount of insulation in inches ( X <sub>2</sub> ) . Given below is EXCEL output of the regression model. Also SSR (X<sub>1</sub> | X<sub>2</sub>) = 8343.3572 and SSR (X<sub>2</sub> | X<sub>1</sub>) = 4199.2672 -Referring to Scenario 14-6 and allowing for a 1% probability of committing a type I error,what is the decision and conclusion for the test H<sub>0 </sub>: \beta <sub>1 </sub>=0 \beta <sub>2 </sub>= 0 vs. H<sub>1 </sub>: At least one \beta <sub>j </sub> \neq 0,j = 1,2 <sup>?</sup> A) Do not reject H<sub>0</sub> and conclude that the 2 independent variables taken as a group have significant linear effects on heating costs. B) Do not reject H<sub>0</sub> and conclude that the 2 independent variables taken as a group do not have significant linear effects on heating costs. C) Reject H<sub>0</sub> and conclude that the 2 independent variables taken as a group have significant linear effects on heating costs. D) Reject H<sub>0</sub> and conclude that the 2 independent variables taken as a group do not have significant linear effects on heating costs.
